The “hey look, we’re cool” drinks came just days after Zinke called Murkowski and her Alaskan colleague Dan Sullivan about her health care vote, which helped sink the Republican effort to repeal the Affordable Care Act. Zinke reportedly implied that Alaska’s economic growth — including future oil and gas development — might hit snags if Murkowski didn’t fall in line. After reports of the calls, lawmakers called for investigations on what they saw as “political blackmail.”

Despite the photo and both politicians’ obvious desire to smooth things over, it’s not all IPAs and smiles yet. On Thursday, the Interior Department’s Office of the Inspector General said it would begin a preliminary investigation into the calls.
